K stands for the dialyzer clearance, the rate at which blood passes through the dialyzer, expressed in milliliters per minute (mL/min) t stands for time. Kt, the top part of the fraction, is clearance multiplied by time, representing the volume of fluid completely cleared of urea during a single treatment.Click to see full answer. Similarly one may ask, how is dialyzer clearance calculated? RESOURCES The equation: (1-exp(koa*(qb-qd)/qb*qd)))/(1/qb-1/qd*exp(koa*(qb-qd)/qb*qd))) Estimate Kt/V from dialyzer clearance. Corrected Standard Kt/V. Kt/V Quick. Gambro Polyflux H Dialyzer Specifications. Gambro Revaclear Dialyzer Specifications. Fresenius Dialyzers. Hemoflow Dialyzers (Fresenius) Additionally, how many types of dialyzer are there? Geometries of Dialyzers There are two types of geometry of artificial kidneys. The geometry refers to the cross sectional area which is in contact with the blood, semipermeable membrane, and dialysate. The first geometry is rectangular. An example of these dialyzers are the parallel plate design. Simply so, what is dialysis clearance? Kt/V. Kt/V, like URR, is a measure of dialysis adequacy. K = clearance—the amount of urea your dialyzer can remove (liters/minute) t = time—the duration of treatment (minutes) V = volume—the amount of body fluid (liters)Why does countercurrent flow within the dialyzer provide the most efficient clearance?The counter-current method is the most efficient because it maintains the same concentration gradient along the entire length of the circuit. The difference in efficiency (in terms of urea clearance) is approximately 20% in modern filters, when comparing concurrent and countercurrent arrangements.
